Completed installation of the stage boxes and 1:3 transformer-isolated microphone splitters for The Ritz in Shawnee. This upgrade enhances stage organization, provides guest performers with convenient access to mic-level splits for their in-ear monitoring systems, and enables isolated outputs for multitrack recording. Additional connectivity to Front of House (FOH) and the main crossover has also been incorporated, allowing visiting engineers to interface seamlessly with the system and operate their own rigs as needed.

Serviced a Vintech 473 that was clipping with the gain set only halfway. After replacing the BC184C transistors, the unit cleaned up significantly, confirmed by a strong, stable sine wave on the test bench. Great to have this piece back in proper working order—working on it brought back memories of the studio days in the San Fernando Valley from 2006–2010.

Spent the weekend replacing all 48 pan pots on a 16 channel Toft ATB console, the circuit was modified to be real pan (stereo 10k linear) rather than the abomination that Toft originally used (mono, wiper grounded). We also installed a new stereo bus from CAPI with Litz 2503 transformers.
